FIELD: pipe line fittings; control of gas flow rate in gas wells.
SUBSTANCE: proposed regulating unit used for wellhead is connected to hydrate-forming inhibitor delivery line; this unit has body where swivel shut-off member is mounted by means of drive shaft which has circular groove and blind radial slot on side of flow-through passage. Circular groove and radial blind slot are interconnected. Surface of body engageable with drive shaft has slot compatible with slot in drive shaft when swivel shut-off member is in open position. This slot is connected with hydrate-forming inhibitor delivery line by means of check valve. Drive shaft has slots before swivel shut-off member which are communicated with circular groove.
EFFECT: enhanced efficiency of introduction of hydrate-forming inhibitor.
